How the calculator works.

Four concepts behind the numbers above.

Step 01

Print on Demand (POD)

Single-copy printing. Zero upfront inventory. Your book is stored digitally and printed only when ordered.

Step 02

Minimum Selling Price

SSP ≈ Production × 2.5

The floor MRP that keeps royalty positive after production cost, marketplace cut, and GST.

Step 03

Marketplace Royalty

(MRP ÷ 2) − Production (GST)

Amazon and Flipkart take ~50% margin on POD books. The rest, minus print and GST, is your royalty.

Step 04

Penray Direct Royalty

MRP − Production − ₹15

Direct sales on Penray's storefront skip the marketplace cut. Only ₹15 handling. Higher royalty per copy.

Questions

Six answers about royalty & pricing.

Stuff most authors ask before they start.

When do royalties actually hit my account? +

On the 10th of every month for sales settled in the previous month, paid via UPI or NEFT. The first payout is in the month following your launch month.

Where can I see live sales numbers? +

You get a private dashboard at /author/dashboard showing units sold per channel, revenue, and projected royalty for the month. Updated daily from each platform's API.

What if a sale gets refunded after I have been paid? +

Refunds settle automatically against the next month's royalty. You will see the reversal as a line item on the dashboard. We never claw back money that has already been paid out — only future months net the adjustment.

Is there a minimum payout threshold? +

No. Even if the month's royalty is ₹50, it gets paid out. We do not hold balances or roll forward — every paise is yours, on time.
